This application is a continuation of application Ser. No. 09/161,584, filed Sep. 28, 1998, now abandoned the entire content of which is hereby incorporated by reference in this application.
This invention relates to a wireless digital transmission system for loudspeakers.
Some wireless loudspeaker systems are known in which an analog audio signal is converted into a frequency modulated signal, this frequency modulated signal being transmitted over the alternating current feeders of a household network. The signal received by the domestic network is then reconverted into an audio signal after extraction of the modulated frequency signal.
Such a teaching is disclosed in particular by patent U.S. Pat. No. 4,829,570. This patent further envisions the use of a compression device to make it possible to compress analog signals delivered by a compact disc reader whose wide dynamic range requires a very wide passband to make the frequency modulated transmission possible. The wide band and the significant deviations pose numerous problems that are solved in this document by the use of a compression circuit to reduce the total dynamic range of the audio signal. This document makes it possible for us already to become aware of a first difficulty, which is the limitation of stereophonic systems, especially using frequency modulation and operating with analog systems such as variable frequency oscillators.
When it is desired to improve simple stereophonic quality to stereophonic quality of the “digital CD” type, the amount of data to be transmitted is such that the passband very quickly limits the frequency modulation.
Finally, this type of system taught by patent U.S. Pat. No. 4,829,570 is acceptable for use for private purposes on the domestic network of a personal residence but can be difficult to implement in a building or even less in communities or commercial groupings. In fact, the music broadcast on the feeder network will be picked up at the same instant by all the loudspeakers installed and connected to the network. This poses a problem in the payment of royalties and it is thus desirable to provide a device that makes it possible to avoid general distribution.
Finally, such a device requires, to have the two stereophonic channels, providing a first carrier frequency for the first channel and a second carrier frequency for the second channel. These frequencies will have to be selected according to very precise conditions, which will also limit the passband possibilities.
A first object of the invention is to propose a wireless digital transmission system for loudspeakers that makes it possible to broadcast stereophonic signals of digital compact disc quality and/or to have remote control.
This first object is achieved by the fact that the wireless digital transmission system for loudspeakers comprises:
A second object is to make it possible to transmit several musical signals intended for different loudspeakers.
This object is achieved by the fact that the serialization means comprise means of inserting a destination address into the packets of serialized signals; and in that the reception means comprise means of comparing the address appearing in the packet received with the specific address at the receiving device to which the loudspeaker is connected.
According to another feature, the serialization device comprises means of multiplexing several fields of digital files representing a different audio signal intended for different addresses.
Another object of the invention is to propose a system that makes it possible to assure that royalties cannot be violated.
This third object is achieved by the fact that the transmission circuits comprise an encryption circuit and the connected receiving device comprises a decryption circuit using a secret key stored in the memory of the deserialization circuit.
According to another feature, the data from the digital signal are serialized according to a protocol comprising a first part consisting of protocol data, a second part consisting of the address of the recipient, a third part consisting of the digital signal or the multiplexed digital signals, and a fourth part consisting of end-of-protocol data.
According to another feature, the protocol comprises a fifth part consisting of control data for the loudspeakers.
According to another feature, the protocol comprises a sixth part consisting of at least one encryption key.
According to another feature, the system comprises means for including control commands in the series signal moving by packet, making it possible to have individual control of each loudspeaker.
According to another feature, the system comprises means of converting an analog signal to a digital signal, placed upstream from the means of compressing the file representing the audio signal, when the audio signal to be transmitted is of the analog type.
Other features and advantages of this invention will appear more clearly from reading the following description made with reference to the attached drawings in which:
The invention will now be described in connection with
The signals are modulated in phase quadrature by circuit (101) on a carrier located between 200 and 300 kHz and are superimposed on the alternating signal of the electric network by transformer (109). The digital audio signals coming from the audio source, after compression, represent a digital data speed of 128 kilobits per second and are processed by microcontroller (102) to be sent by successive packets according to protocol (EP) explained above.
Microcontroller program (102) can be adjusted to perform multiplexing of several audio sources, making it possible, e.g., to send a piece of classical music to a first loudspeaker while sending at the same moment a piece of jazz music to a second loudspeaker, each having a specific address and its own decryption key.
In this case, device (10) addresses one or more fields to a user identified by a card or a package (11) connected to the loudspeaker. Transmission device (10) and receiving device(s) (11) are not connected to each other except by electrical conductors of the domestic network for feeding electricity.
Finally, the operating program of microcontroller (102) makes it possible, when it receives commands sent by a remote control box (12) transmitting, e.g., a wave signal to a sensor (1020), to include the commands thus generated by this box (12) in the packet so as to constitute control data for the loudspeaker. These control data make it possible to individually adjust each loudspeaker by adjusting the right channel, the left channel, the base, the treble, the volume etc.
When it is desired to protect audio data being moved on the domestic network so as to make it possible to collect royalties and prevent the same musical piece being able to be heard by persons not having paid the royalties, an encryption circuit (103) is added to the device, placed between compression circuit (104) and microcontroller (102). In the case where the source of the musical signals is not of the “digital” type, an analog-digital converter (106) is connected to the device and it receives at its input the output signals of an analog amplifier (107) that receives the analog audio signals.
Receiving device (11) consists as before of a first transformer (118) making it possible, with the help of a rectification circuit, to feed a feed circuit (110) intended to generate the feed signals necessary for the operation of the various circuits of receiving device (11). A second transformer (119), connected to the primary winding of the first transformer with the help of a decoupling capacitor, feeds a demodulator (111) with phase quadrature, which provides, at its series output, the signals of the protocol and the protocol packets to a microcontroller (112) that converts these series signals into parallel signals going to a decryption circuit (113) whose output is connected to a decompression circuit (114). The output of decompression circuit (114) is itself connected to a digital-analog conversion circuit (115) whose output is intended to feed a loudspeaker (LS). The compression and decompression circuits, by an amplifier (116), use an algorithm of the “MPEG” type at level 3 and encryption circuit (103) and decryption circuit (113) use an algorithm of the “MMPP” type (Multimedia Protection Protocol).
The memory of microcontroller (112) of package (11) has stored in it the identification address that makes it possible to compare its address to the address received in the packet to identify if the digital audio data are intended for it or for another loudspeaker. Likewise, the memory of the microcontroller has stored in it, during initialization or manufacture, the decryption key. Storing the decryption key during initialization can be done thanks to a fourth zone of the protocol.
The analog-digital conversion circuits (CAD/or CDA) for encryption compression and amplification of transmitting device (10) can be made, e.g., of a digital signal processor sold by MOTOROLA under reference 563XX and generally called “D.S.P” (Digital Signal Processor).
Likewise, decryption, decompression, and digital-analog conversion circuits of receiving device (11) can be made of a digital signal processor sold by MOTOROLA under reference 563XX and generally called “D.S.P.” (Digital Signal Processor).
Thus it can be possible, thanks to such a device, to install multiple loudspeakers in different locations provided that they be fed by the same phase of the network to which transmission device (10) will be connected. This transmission device (10) will have to be connected, on the one hand, to an audio signals source that could be, e.g., the digital output of a compact disc reader or even the digital output of a hard disc of a jukebox such as the one described in
Any other central unit having equivalent or higher performance could be used in the invention.
This central unit commands and manages a sound command circuit (5), a telecommunications command circuit (4), an input command circuit (3), a mass storage command circuit (2), a display means command circuit (6). The display means comprise mainly a video monitor (62) with a 14 inch (35.56 cm) flat screen without interlacing of the SVGA type with high resolution and low radiation, it is this monitor that is used to reproduce images (e.g., album covers of musical selections), graphics or video clips.
Means of mass storage (21) using high speed, high capacity, hard discs of the “SCSI” type are connected to storage means already present in the microprocessor device. These means are used to store digitized and compressed audiovisual data.
A high speed, 28.8 kpbs telecommunications modem adaptor (41) is integrated to make possible the connection with the audiovisual data distribution network controlled by a central server.
To reproduce the audio data of musical selections, the system comprises loudspeakers (54) receiving amplifier-tuner signal (53) connected to an electronic circuit (5) of the “music synthesizer” type provided to support a large number of input sources while providing an output having “CD” (compact disc) quality, such as, e.g., multimedia audio adapter with microprocessor of the “Sound Blaster card” type SBP32AWE of Creative Labs Inc. to which two memory buffers (56, 57) are added for the purpose explained later.
Likewise, the command circuit of the display means also comprises two buffer memories (66, 67) for the purpose explained below.
A distributed, thermally regulated feed of 240 watts provides the energy of the system. This feed is protected against surges and over-oscillations.
The audiovisual reproduction system manages, by its input controller circuit (3), a 14-inch (35.56 cm) tactile screen (33) “Intelli Touch” from Elo Touch Systems Inc., which includes a screen covering panel using “advanced surface wave” technology and a bus controller of the “AT” type. This tactile screen makes it possible, after having displayed on video monitor (62) or a television screen (61) various selection data used by the clients and some selection data used by the clients and command and management control data used by the manager or the proprietor of the system. It is also used for maintenance purposes in combination with an external keyboard (34) that can be connected to the system that has, for this purpose, a keyboard connector, controlled by a key lock (32) through an interface circuit (3).
Input circuit (3) also interfaces with remote control system (31) consisting of, e.g.,:
A device for royalties payment (35) from National Rejectors Inc. is also connected to input interface circuit (3). It is also possible to use any other device that makes it possible to receive any type of payment by coins, bills, tokens, magnetic cards with chips or a combination of payment means.
To support the system, a frame or a stand made of steel with external fittings that can be personalized is provided.
Besides these elements, a wireless microphone (55) is connected to sound controller (5), which makes it possible to transform the latter into a powerful system for announcements and information intended for the public or possibly for a karaoke machine. Likewise, a wireless loudspeaker system can be used by the system.
Remote control unit (31) makes it possible for the manager, e.g., behind the bar, to access and control various commands such as:
Two buffers (56, 57) are connected to sound controller circuit (5) to make it possible to store, each in alternation, data corresponding to a quarter of a second of sound. Likewise, two buffers (66, 67) are connected to video controller circuit (6) each capable alternately of storing a tenth of a second of images. Finally, a respective buffer (46, 36, 26) is connected to each communication controller circuit (4) for input (3) and storage (2) interface.
The digitized and compressed audiovisual data are stored in memory means (21).
These data are transmitted by a central unit (1) to card (105) on which elements have been added that correspond to circuit (10), encryption circuit (103) having been directly connected to buffer circuits (56, 57) in the case where the data are already compressed, either by a first connector (1021), bypassing encryption circuit (103), if the data are already encrypted or do not need to be, or by a second connector (1031) using encryption circuit (103), if the data are to be encrypted. In the case where the data are not compressed, buffers (56, 57) will be connected to a third connector (1041) to use the compression circuit.
Thus, by connecting the output of transformer (108) to the electric network, it will be possible, by connecting receiving circuits (11) at different points in the network, to feed various loudspeakers remotely, besides loudspeakers normally provided in jukebox system (54). This will make it possible to have good quality sound broadcasting in various places while assuring the manager the possibility of regulating the volumes according to the locations or according to the arrangements of the loudspeakers.
In the case where the invention is used in another device such as a compact disc reader, a radio for receiving specialized stations, etc., it is possible to equip the payment device with the help of one of the payment means mentioned above for jukebox application which, like for the jukebox, does not allow the receiving device to operate except when the royalty has been paid and for the time allotted for the royalty. This period is determined by a clock connected to the receiving device.
Other modifications within the reach of one skilled in the art are also part of the spirit of the invention.
